LOOK FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 441,949, dated December 2, 1890.

Application filed July 21, 1890.

To a/ZZ whom it may concern.-

Be it known that I, GEORGE R. FULLER, of Rochester, in the county of Monroe and State of NewYork, have invented a new and useful Improvement in Looks for Bicycles, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

My invention is an improved lock for bicycles or other velocipedes, by means of which the wheel of the vehicle may be conveniently and rigidly held from turning by applying the locking device preferably to the periphery of the Wheel.

The invention is hereinafterfully described, and particularly pointed out in the claims.

Referring to the drawings, Figure lis a side elevation of aportion of the fork and the wheel of a bicycle with my improved lock in place, parts being omitted; Fig. 2, a view of the device seen as indicated by arrow fr in Fig. 1, parts being broken away and the lockingclamp bearing against the wheel; Fig. 8, a cross-section of the fork taken on the dotted line 3 3 in Fig. l; Fig. 4, a section taken as on the dotted line Il 4r in Fig. 1. Figs. 5 to 8, inclusive, show the device with various pieces successively added; Fig. 9, a section taken as on the dotted line 9 9 in Fig. 1, parts being omitted; and Fig. 10, a view of the clamp, showing the corrugations.

Referring to the parts shown, A is the wheel of a bicycle or other velocipede, and B the fork, to which latter part my improved lock is shown as being secured in position to bear upon the periphery of the Wheel.

The lock is provided with a frame C to se cure it to the fork, said frame being secured to the fork by means of a lip o and .bindingscrews b b.

cis a sliding clamp turned laterally over the wheel to press the latter, as shown in Fig. 2. -This clampis in one piece or rigid as to its parts, and rests in the circular inclosingcase d of the lock, and is formed with an opening e within said case and internal gearteeth f,Figs. 1 and 5. At the opposite side the clamp is formed with external ratchetteeth g, which are engaged by a spring-pressed pawl h within the case. Centrally within the case is a barrel or cylinder i, rigid with the Serial No. 359,390. (No modell) case, whose axis coincides with the axes of the case.

k, Fig. 5, is a pinion occupying the opening c in the clamp, having its teeth engaging the internal teeth of the clamp to actuate the latter, said pinionbeing concentric with and held to turn on the barrel t'.

Z is a wrench or handle outside of the case, secured rigidly to the pinion by fasteningscrews `n n. By means of this handle the pinion may be turned at any time in a manner to bring the clamp firmly down upon the wheel, as shown in Fig. 2, to firmly lock the Wheel and prevent it from turning on its axis.

The ratchet-teeth are formed in such a manner that the clamp may be moved freely toward the wheel, but will be prevented bythe pawl from moving in the opposite direction. Then to lock the wheel it is only necessary to turn the handle l--as, for instance, from the position shown in full lines in Fig. 8 to the position shown in dotted lines in the figurethe pawl holding the clamp in position against the wheel.

Within the cylinder i is placed a movable core o, consisting of tumblers or partsof a look of suitable kind to be operated bya key or instrument separate from the lock, carried in the pocket of the rider of the vehicle, which parts, however, within the cylinder and the key by themselves, form no part of my invention. A

Beneath or back of the clamp c is shown a sliding piece p, Fig. l, constituting an actuator for the pawl, provided with a rigid pin r to bear against the pawl in a nia-nner to turn the latter awayfrom the clamp. This sliding piece has a part s extending nea-r to or within the cylinder, so that the sliding piece may be moved against the pawl by the key, the latter being inserted inthe key-hole t. The piece pis provided at one end witha slender spring o to hold it normally back from the pawl, so that the latter may be freeto engage the clamp. Now to unlock the bicycle it is only necessary to insert the key in the core o and turn the actuator p against the pawl to release the clamp. The pawl is pressed against the clamp by a spring u, rigid with the case d.

The case d is open at one side,.but formed IOO frame C by short clainping-screws'w, Figs. 1 and 9, passed through the back@ and threaded in the frame. Y. Fig. 5 shows a thin circular plate or diaphragm a', placed against the clamp@ and formed with holes h over the screws w. Resting upon this diaphragm is the pinion 7o, the toothed portion of which is within the space e of the clamp, as above described. The ring or part c'V of the pinion is formed with a peripheral groove, as shown in Fig. 4, and an involute spring d occupies said groove in part, having its inner end inserted in the pinion. This spring has its outer end inserted in a 4hole e" in the diaphragm, and a pin f', rigid with the case and projecting through the diaphragm, also serves to hold the spring.

g,Figs. 6 and 4, is a thin plate placed over the spring d to inclose the latter between the plate and the diaphragm. This plate rests against a circular shoulder ot' the pinion and serves when .in one position as a dust-guard to cover openings leading into the i-nterior of the case. This dust-guard is held to turn upon its bearings on the pinion, and is provided with a rigid pin 71,', by means of which it may be turned. It is also formed with holes w, which register with the holes b in the diaphragm when the Ydust-guard is in a certain position. Outside of the dust-guard is the circular cap or cover t" for the case, held rigidly to the latter Vby screws 7a. This cap is also formed with holes Z', registering with the holes ZJ in the diaphragm, through which an instnument may be passed to turn the screws w. with extensions n on opposite sides to accommodate the pin h in the dust-guard,so that the latter may be turned at any time to either cover or uncover the holes Z in the cap 'i'. As shown in Figs. 7 and 8, the pin is turned to the left, and the holes Z, leading into the interior of the inclosing-case, are closed. Fig. 6 shows the dust-guard in full lines turned to the right, in which position the holes w register with the holes b of the diaphragm and l of the cap fi. VThen these holes all register and the clamp is raised out of the'fway, a screw-driver may be passed through them to turn the screws uf te remove the case from the frame C.

The dust-guard is formed with peripheral notches o', Fig. 6, so as to clear the screws kr', which pass through it and admit of its being turned, as above described.

The screws 7o', that hold the cap t" to the case d, are threaded in the formerl and have their heads resting in countersink-openings One of the holes Z is formedV the Wheel is locked and left standing no person can loosen said screws 'w and remove the case from the frame C to unlock the wheel.

I t'orm the frame with a perforated projecting lug p at its rear surface, Figs. 2 and 3. This lug issformed with an opening fr', and the clamp is provided with a pin s to enter said opening when the clamp is brought down upon the wheel to lock the latter. By this contrivance links t of a chain may be held by the pin, so that the vehicle may be chained to a post or other iixed part (the chain passing around said post or fixed part) at the same time that the wheel is locked by the clamp. I form the surface of the clamp in contact with the wheel with teeth or corrugations u', Fig. lO, to sink into the rubber tire of the wheel, so as to more firmly hold the latter. The involute spring d', acting upon the pinion, serves tov throw the clamp up off the wheel when the clamp is released from the holdingpawl by the key, as above stated.
